General information about Pixhawk designs, schematics, reference hardware, FMU versions, licensing, and trademarks, and contributing to the project can be found in the repo README.
This is the first Pixhawk FMU design, and was intended to be used with various piggyback boards, including an IO board (the boards were combined into one package for the FMUv2 design).
Warning This design is end-of-life.
The design is provided in EAGLE CAD files (can be viewed with the free version).
It consists of schematic files (*.sch) and includes open reference hardware PCB layouts (.brd). BOM management is performed using Bob Starr's BOM-EX plugin.
